Facilitating Changes In College Teaching Practices: Instructional Reform, Identity Conflict And Professional Community In A K-20 Partnership, Stacy Olitsky Oct 2015

Facilitating Changes In College Teaching Practices: Instructional Reform, Identity Conflict And Professional Community In A K-20 Partnership, Stacy Olitsky

Stacy Olitsky

In this paper, I explain variation in the adoption of student-centred teaching practices among college faculty members in a program designed to promote K-20 instructional reform. I analyze data from a qualitative study of a Math and Science Partnership in order to understand why some faculty members had undergone extensive changes to their practices whereas others had not, even though both groups had demonstrated changes in their beliefs. Findings show that when collective identities focused on reform become more salient than the role identities associated with their teaching positions, faculty members are able to persist through the loss of self-efficacy ...

Pre And Post Survey-Based Prediction Of Results From Student Characteristics, Jared Estad, Michael Kuehn, Jeremy Straub, Eunjin Kim

Jeremy Straub

This study was created to compare a large data set of students class surveys. In this data set, there exist both pre- and post-survey data. A set of knowledge based questions exist at the end of the survey. Our intention is to use the other data with in each survey to predict based on a singular set of pre-survey data a students potential for success throughout the course. As such, we need to account for data on the pre-survey and its knowledge based questions. Then, we need to account for how this data may interact with the data on the ...

Involving undergraduate students in bona fide research can provide multiple types of benefits. Whether students elect to pursue research careers or not, research experiences can be beneficial. Students gain an excellent resume item and interview discussion topic. They also gain experience in team participation dynamics and project management and the opportunity to put techniques that they have learned in the classroom to use. In interdisciplinary projects, they learn to work with those from other disciplines, gain an understanding of the challenges of doing so and gain an understanding of the vernacular of these other disciplines.

Assessment Of Educational Expectations, Outcomes And Benefits From Small Satellite Program Participation, Jeremy Straub, Ronald Marsh

Jeremy Straub

This paper begins to characterize the educational outcomes that can be produced from student participation in a small spacecraft development program. We asked students what benefits they expected to receive from program participation and we asked them, at the end of the semester, what benefits they had received. We also characterized student performance through the use of post-participation Likert-like scale questions and the use of a widely-used questionnaire for assessing student research participation outcomes. We compare benefit expectation and attainment, characterize the level of benefits received across multiple types of participation and assess the effect of program participation on subject-specific ...

Educational Outcomes From The Openorbiter Small Spacecraft Development Program, Jeremy Straub Dec 2013

Educational Outcomes From The Openorbiter Small Spacecraft Development Program, Jeremy Straub

Jeremy Straub

The OpenOrbiter program [1] is developing a low-cost framework for the creation of space-craft by researchers and educators worldwide [8]. In addition to the technical objectives, ed-ucational assessment [2, 3] has also been a key focus. Students working on development of the spacecraft [4] were asked what types of benefits they sought from their participation [5]. The assessment of the attainment of these benefits is ongoing, in conjunction with continued development in pursuit of the crea-tion of a set of designs that can be used to build a spacecraft with a cost of under $5,000 [13] .


Increasing National Space Engineering Productivity And Educational Opportunities Via Intrepreneurship, Entrepreneurship And Innovation, Jeremy Straub Dec 2013

Increasing National Space Engineering Productivity And Educational Opportunities Via Intrepreneurship, Entrepreneurship And Innovation, Jeremy Straub

Jeremy Straub

Research and educational efforts related to space engineering or requiring access to space face significant startup costs. The cost of developing a 1-U (10 cm × 10 cm × 11 cm) CubeSat from scratch can be approximately $250,000. Those buying a kit must pay amortized vendor development costs on a per-mission basis, creating a lower per-mission barrier. Kit users are also constrained by being unable to make changes to vendor subsystems without incurring substantial redevelopment costs or vendor charges. The Open Prototype for Educational NanoSats (OPEN) is changing this by providing freely available design documents for a 1-U CubeSat class spacecraft ...

Openorbiter: Analysis Of A Student-Run Space Program, Jeremy Straub

Jeremy Straub

Students at the University of North Dakota, as part of faculty-mentored teams in a student-lead program, are working to broaden participation in humanity's exploration of space. The OpenOrbiter Small Spacecraft Development Initiative (OSSDI) is demonstrating two complementary paradigm-changers. First, the initiative facilitates student involvement in all aspects of a space program, without the preconceptions present in established space activities. Second, it is demonstrating a low-cost framework for small spacecraft development. These combined activities are poised to demonstrate a new way forward for space exploration: combined, they allow risk-taking exuberance and a cost of entry that makes risk-taking exuberance acceptable ...


Using Plankton Imaging Technology And Computer Science For Biological Oceanographic Advancement And Education, Adam T. Greer Feb 2013

Using Plankton Imaging Technology And Computer Science For Biological Oceanographic Advancement And Education, Adam T. Greer

Adam T. Greer

Oceanography is an inherently interdisciplinary subject that combines observations of physics, biology, chemistry, and their interactions. While most physical and chemical measurements can be made on small scales (cm to m) through the use of sensors (temperature, salinity, pH, etc.), traditional tools to understand the biology of the ocean have only allowed for coarse sampling resolution (i.e., plankton nets sample large portions of the water column). New imaging technology enables the biological component of the ocean to be sampled on the same scale as the physical and chemical, allowing scientists to finally address the interactions among different oceanographic processes ...


An Open Prototype For Educational Nanosats: Increasing National Space Engineering Productivity Via A Low-Cost Platform, Jeremy Straub Feb 2013

An Open Prototype For Educational Nanosats: Increasing National Space Engineering Productivity Via A Low-Cost Platform, Jeremy Straub

Jeremy Straub

The Open Prototype for Educational NanoSats (OPEN) is poised to allow a dramatic increase in the number of students, worldwide, that have the opportunity to participate in hands-on spacecraft development. It is designed to facilitate the formation of CubeSat development programs via providing a publically-available set of spacecraft design documents, implementation and testing plans. These documents should allow the creation of a 1-U CubeSat with a parts budget of approximately $ 5,000. This allows spacecraft development to be incorporated in regular curriculum and supported from teaching (as opposed to research) funds.

The International Trafficking In Arms Regulations: Precluding Innovation In Academic Spacecraft Engineering — Or Are They?, Jeremy Straub, Joe Vacek Feb 2013

The International Trafficking In Arms Regulations: Precluding Innovation In Academic Spacecraft Engineering — Or Are They?, Jeremy Straub, Joe Vacek

Jeremy Straub

Government regulations and uncertainty about their enforcement can be a significant barrier to innovation. In business, it is undesirable to consume time and other resources developing a product that cannot be sold or which requires navigating significant bureaucracy for each sale. In academ-ia, where limited funding is available prior to the submission of a grant pro-posal and receipt of an award, proposal-stage compliance costs can derail a project long before it begins. This paper reviews the International Traffick-ing in Arms Regulations (ITAR) and their impact on spacecraft research in academia, private research labs and industry. It reviews the exemptions available ...
